JOHN MASSEY, OF ANDERSON, INDIANA.

ELECTRIC MOTOR OR ENGINE.

SPECIFICATION forming part of Letters Patent No. 726,177, dated April 211903.

Application filed December 2,1901. Renewed December 10, 1902- Serial No.134,705. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN MASSEY, a citizen of the United States, and aresident of Anderson, in the county of Madison and State of Indiana,have made a certain new and useful Invention in Electric Motors orEngines; and I declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it appertains to make and use the invention, reference beinghad to the accompanying drawing, and to letters of reference markedthereon, which forms a part of this specification.

The drawing shows the invention as applied, the motor, being in sideelevation.

The invention has relation to electric motors or engines; and itconsists in the novel construction and combinations of devices, ashereinafter set forth.

In the accompanying drawing the letter (t represents the working shaftof the engine, having a fly-wheel b and a crank c, which is connected bymeans of a pitman d to a reciprocatory armature-rod e,for which guidebearings or perforations g are provided in the opposite standards of theframe it, to the ends of which are secured the electromagnets 7c and itwithin said frame it. These electromagnets have their cores in alinementand are connected to the battery or source of electricity m by wiring.The armature between the electromagnets is an arm or plate 19, carriedby the bar 6 and which projects between the oppositely-facing ends ofthese magnets. This armature is rigidly connected to said bar 6 and atits end engages the fork at the end portion of a shifting lever g, whichis intermediately pivoted to the framing and has its opposite endportion in sliding contact with the terminal contacts 8 and s of theswitch, which are disconnected from each other, but have their ends inapproximation. A binding-post t is also connected to the framing. Theseparts-that is to say, the switch-lever q, the switch-bearings, and thewire connection t-are all properly insulated. The wiring of theelectromagnet 7c is indicated at w and that of the magnet 70 at 20.

One terminal of the wiring to is connected to the switch-bearing s, andthe other terminal of said wiring is connected to the binding-post t.One terminal or energizing wire a of the battery is connected to thecommon binding-post t, while the other terminal wire, a, of said batteryis connected with the arm 0* of the switch-lever q.

The operation is as follows: The switch-lever being on theswitch-contact s, the electromagnet 10 is energized to move the armaturep, the bar 6, and the crank of the engine and the fly-wheel. As thisrotary motion continues through the momentumvof the fly-wheel thearmature p is moved in the opposite direction and disengaged from thecontact 8, engaging the bearing 8, so that the electromagnet 70 becomingenergized draws the ar mature in the opposite direction and controls themovement of the bar 6, crank, fiy-wheel, and operating-shaft.

This engine is mainly designed for use in operating toys and lightmoving machinery.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In an electric motor or engine, the opposite perforated standards, theopposite electromagnets within said standards, and having their cores inalinement, the reciprocatory armature-rod engaging the perforations ofsaid standards, the driven shaft having an operating connection withsaid rod, the armature rigidly affixed to said rod, the terminalcontacts, the terminal post, the intermediately pivoted switch-leverhaving an operating connection with said armature at one end thereof,and adapted to engage said contacts at the opposite end portion thereof,and the electric battery having terminal connections with said lever andpost, said magnets having terminal connectionswith said post andcontacts, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN MASSEY.
